I am using Sanyo Eneloop (2 sets) currently in my Sunpack 383 auper auto flash. I also tested them in my Fuji S9100 and they really work great. Wiondering if the technology in this battery can be made in higher mAh, and if everyone has heard if Sanyo may make a 2500or 2900mAh version down the road.

Thans to T-Cav and Jim C for recommendations to get these batteries they work perfectly in my flash cutting recharge cycle time in half
